Abstract: High-spin states of 162Lu have been produced and studied via the 147Sm (19F,4nγ) 162Lu reaction. In-beam γ-rays were measured by using 1 planar detector and 7 high-purity Ge detector with BGO anti-Compton shield. The level scheme of the yrast band in 162Lu was established for the first time and the signature inversion in energy was discovered at the low rotational frequencies. The yrast bands of doubly odd nuclei in the A=160 mass region have been reinvestigated and the systematics of signature inversion is briefly discussed.
